Hi, The dsrom math font only works partially with MKIV, and I do not understand what is happening. Consider the following example from http://wiki.contextgarden.net/Doublestroke (which I wrote, after suggestions on the mailing list).

I think in the font handling because \loadmapfile[dstroke.map] \starttypescript [math] [modern,computermodern,latinmodern,ams] [size] \definebodyfont [17.3pt,14.4pt,12pt] [mm] [mr=dsrom12 sa 1] \definebodyfont [11pt,10pt,9pt] [mm] [mr=dsrom10 sa 1] \definebodyfont [8pt,7pt,6pt,5pt,4pt] [mm] [mr=dsrom8 sa 1] \stoptypescript \definetypeface [modern] [mm] [math] [modern] [ams] [encoding=texnansi] \setupbodyfont[modern,10pt] \definefamilysynonym [default] [doublestroke] [mr] \def\dstroke{\fam\purefamily{doublestroke}} \def\doublestroke#1{{\dstroke#1}} \starttext $\doublestroke{E} \doublestroke{1}$ \stoptext works with MkIV (I used mr).

I think in the font handling because
[snip]
works with MkIV (I used mr).
I am now really confused. I thought that mr was just like any other math family, just predefined to a default. But the above example shows that this is not the case. Of course, I cannot use mr=dsrom in a complete document, since mr is the math roman font. Aditya

Thanks. I never understood why one needed to define such things using familysynonyms. The above defintition makes more sense. I will clean up the wiki examples for using other fonts.
\starttext $\doublestroke{E} \doublestroke{1}$ \stoptext
indeed does not give a dstroked 1 ... i wonder why; maybe something with the mathcodes
But why does it work if I replace mc by mr (as Wolfgang showed). Also, how can I check the mathcode of a character, other than going through the sources and figuring out where it is set. Aditya

Thank you. After making this change and regenerating formats, the dsrom works correctly for both the test document and my actual document. Aditya
